To all wlwm it may conce'n:

Be it known that I, J Ani: BAzELL, citizen of the United States, and resident of New York, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Shock-eutralizers, of which the following is a specification.

My invention relates to devices for neutralizing, and eliininating to as great an exthe effect upon the body of an automobile or similar vehicle of shocks transmitted from the wheel of the vehicle due to irregularities in the roadbed; and the objects of my invention are to provide a shock neutralizing device in which the shocks are not transmitted to the body of the vehicle, and one in which vertical movements of the wheel of the vehicle due to passing over a projection or falling into a depression in the roadbed are not accompanied by a concomitant Vertical movement of the body of the vehicle, and to provide a device in which the range of Vertical movement of the body of the vehicle permitted by the springs in the normal operation thereof and at times wlien excessive irregularities in the roadbed are not encountered, is reduced to a minimum.

lVith the above and other objects of invention in view, my invention consists in the improved 'hock neutralizing device illustrated in the accompanying drawing, described in the following specification, and claimed in the clauses of the concluding claim, and in such variations and modifications tliereof as will be obvious to those killed in the art to which my invention reates.

In the drawing accompanying and forming a part of this application and wherein the preferred embodiment of my invention is illustrated: Figurc 1 is a view illustrating my improved shock neutralizing device in plan and showin the manner in which the same is connecte with the frame Aof an automobile or similar vehicle; Fig. 2 is a view showing the shock neutralizin device and a portion of the frame in si e elevation; and Fig. 3 is a view showing a section taken upon a horizontal plane indicated by the line 3-3, Fig. 2. i

Referring to the drawing upon which the same reference numerals designate the same the numeral '5 designates a portion of the frame of an autoinobile or similar vehicle and upon which the body is supported, and 6 designates a suitable bracket which is connected with the axle of the vehicle in any way and either directly or indirectly, and which bracket partakes of the Vertical movements of the axle, as will be understood.

Supported from the bracket 6 is a double elliptic spring comprising two oppositely located spring members 7, 8, each of wliich members is commonly made up of a plurality of leaves as is usual in spring construction and the ends of which members are connected with one another in any way, as, for example, either directly as shown at 9 or through an intervening link 10.

The reference nuineral 11 designates a rocking lever pivotally supported intermediate its ends upon a stud 12 which forms a fulcrum for the lever and which stud is located at the lower end of a bracket 13, which bracket in turn is connected with the frame 5; from which it will be seen that the frame and the body of the ported from the lever 11 through the Stud 1'2 and the bracket 13 which carries said stud, and that the spring members are not themselves directly connected with the frame; the connection between the frame and spring being efl'ected through the bracket 13, lever 11 and the other elements of the shock neutralizing device hereinafter referred to.

The reference nuineral 14 designates a bracket or stirrup carried by the upper spring member 7 and with which the upper end of a vertically extending rod 15 is pivotally connected as shown at 10, said stirrup being shown as held to the spring member by means of clips 17. This rod extends loosely through an opening provided iii an abutment 18 carried by the left hand end of the lever 11, see Fig. 3' and the nu-inei'als 19, 20 designate two coil Springs surrounding the said rod, the adjacent ends of said Springs abutting against opposite sides of the said abutment and the remote ends thereof abutting against two stops 21 carried by the rod. The rod is preferably threaded -and the stops forined by nuts in threaded engagement with the rod, and intervening washers as shown, so that by varying the position of the nuts upon the rod the vehicle are supferred to.

degree of compression to which the Springs 19, 20 are sub1ected may bc varied, as will be understood.

The right hand end of the lever 11 carries an abutment 22 similar to the abutment 18 and having an opening through which the upper end of an inclined rod 23 extends, and in which it fits loosely; and 24, 25 designate two coil 'springs surrounding the said rod, and the adjacent ends of which abut against opposite sides of the abutment 22, while the remote ends of these Springs abut Vagainst stops 26, similar to the stops 21 above re- The lower end of the rod 23 is pivotally connected to the lower spring, or to any other suitable part of the running gear. In the present instance, it is connected at 27 with a bracket or stirrup 28, which stirrup is held in a fixed position relative to the lower spring mem r 8 in any suitable way as by means of clips 29 which, in the embodiment of my invention illustrated, secure the bracket 6, spring member 8, and said stirrup together. The abutments 18 and 22 are provided with studs which extend through holes provided in the lever 11, as best shown in Fig. 3, whereby rocking connections are provided between the abutments and the lever, as will be understood.

The forward end of the spring members 7, 8 is preferably connected with the frame 5 through a suitable connection which acts as a radius bar or link, and, in the drawing, such a connection is shown as accomplished by providing the spring member 8 with a leaf hang a forwardly extending portion 30 the free end of which is connected to a stud 31 carried by the frame member 5.

The rods 15 and 23, the coil Springs 19, 20, 24 and 25, the rocking lever 11, and the stud 12 which, at the instant when a shock occurs, forms a fulcrum for said lever, constitute shock neutralizing or absorbing elements of my device; while these same elements form transmission mechanism through which the weight of the body is transmitted to the spring members 7,'8 in such a way as to 'reatly reduce the Vertical movement of the ody during the normal operation of the vehicle and ,when no shocks are encountered, at which times the abutment 22 forms the fulcrum of the lever.

'When in use the coil Springs 19, 20, 24 and 25 are laced under imtial compression to such a egree that in the normal running of the vehicle and when theidevice is not operating to neutralize the effect of shocks none of them will be further compressed, at which time the weight of the body will be transmitted through the frame 5,bracket 13,1ever 11 and rod 15 to the spring members 7, 8, the abutment 22 then acting in efl'ect as the fulcrum of the lever and the coil Springs 19, 20, 24 and 25 aotin in efi'ect as rigid members. Under such con 'tionl and so long'al no large obstructions or irrcgularitics iu the road are'encountered the supporting spring members T, 8, are the only Springs in action, and these s n'ing members support the body of the vehicle and act in the same way as though the shock absorbing springs above referred to were not present except that the Vertical movements of the body will be rcduced in magnitude because of the use of the swinging lever, the Vertical movement of the 'bracket 13 being less than one-half the vertical movement of the rod 15 when the proportion of the parts is as shown in the drawing. If, however, a projection is encountered in the road the effect upon the elements herein described.is to force the axlc and the bracket upward, which movement is transmitted through the rod 23, spring 25, lever ll, spring 20, and rod 15 to the upper spring member 7, which member is thus moved` downward; the stud 12 tending to remain in whatever position it is in at the instant a shock is transmitted through the parts herein referred to because of the inertia of the frame with which the bracket 13 is connected and the body carried by the frame, while the spring member 7 is readily moved because of its small mass. This movement of the spring members 7 and 8 toward one another and the accompanying movement of the free ends of the lever 11 in opposite directions about the stud 12 as a fulcriun, will be accompanied by no or by a minimum vertical movement of the bracket 13 and the body of the vehicle because of the inertia of the body. On the other hand, if the wheel of the vehicle drops into a depression the bracket 6 moves downward, and motion is transmitted through the rod 23, spring '2-1, lever 11, spring 19, and rod 15 to the upper spring member 7, which member is thus moved upward; but this movement of the spring members 7 and 8 away from one another and the accompanying movement of the free ends of the lever 11 in opposite directions about the stud 12 as a fulcrum, will for the same reason be accompanied by no or but little Vertical movement of the bracket 18 and the body.

The Sudden and abnormal movement of the spring members 7 and 8 toward or awaV from one another, as projections or depressi'ons are encountered in the road, may ohviously occur at the instant when the spring member 7 is in the upper, the lower, or anv intermediate position which it assumes durin .the slow vibratory movements of the ve icle body during normal operation and when shoeks due to obstructions or depressions have not to be absorbed or neutralized. Such abnormal movement` however, will always act to move the free ends of the lever 11 in opposite directions about the stud 12 as a temporarilv fixed fulcrum2 irrespective of the vertical position occupied by the stud and bracket at the instant when the effcct of a shock is to be neutralized, which movenient', however. is in no case accompanied by a concomitant vertical movement of the bracket and body.

The above expianation does not take into account the resilience of the coil springs through which movemcnt is imparted to the upper spring member 7 as the spring members move simultaneousb' toward or from one another. Of course a part of the shock transmitted from the bracket 6 will always be absorbed by those of the coil Springs through which movement is or tends to be transmitt'ed in the manner above explained, thus reducin the range of movement of the spring mein ers toward or from one anothe and, if the shocks are not excessive` the)7 will be entirely absorbcd by the coil Springs, in which case no movement of the upper spring member occurs.
